Question

part b
write an energy reaction equation for an active bear (during summer).
inputs -> outputs + energy

Explanation:

Step1: Identify the process

Bears (like other animals) use cellular respiration to convert food (organic matter, e.g., glucose from consumed plants/animals) and oxygen into energy, carbon dioxide, and water. The general formula for cellular respiration is \( \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{Energy (ATP)} \). For an active bear in summer, it's consuming food (inputs: organic compounds like glucose, \( \text{O}_2 \)) and producing outputs ( \( \text{CO}_2 \), \( \text{H}_2\text{O} \)) plus energy (ATP for metabolic activities).

Step2: Formulate the energy reaction equation

Inputs: Food (e.g., Glucose, \( \text{C}_6\text{H}_{12}\text{O}_6 \)) + Oxygen ( \( \text{O}_2 \) )
Outputs: Carbon Dioxide ( \( \text{CO}_2 \) ) + Water ( \( \text{H}_2\text{O} \) ) + Energy (ATP)

So the equation is: \( \text{Glucose (or Organic Matter)} + \text{O}_2
ightarrow \text{CO}_2 + \text{H}_2\text{O} + \text{Energy (ATP)} \) (more precisely, using the chemical formula for glucose: \( \text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{Energy (ATP)} \))

Answer:

The energy reaction equation for an active bear (during summer) is \( \boldsymbol{\text{C}_6\text{H}_{12}\text{O}_6 + 6\text{O}_2
ightarrow 6\text{CO}_2 + 6\text{H}_2\text{O} + \text{Energy (ATP)}} \) (or in general terms: Food + Oxygen \(
ightarrow \) Carbon Dioxide + Water + Energy)
